When should the sewage treatment plant be repaired?
To improve the treatment process, it is not always necessary to create a new treatment plant. Sometimes it is possible to improve the performance of the treatment plant by modifying the existing sewage treatment plant. In a treatment plant, sometimes the processes are not designed properly. Sometimes the order of the purification processes may not be correct and sometimes the type of wastewater or effluent produced from the industrial, sanitary or urban unit may have changed.
Of course, sometimes there is a possibility that all the things mentioned above are correct, but the devices have problems or need to be repaired. In these cases, the possibility of environmental issues and water and soil pollution should be reduced by modifying the wastewater treatment plant. The best way to determine if the treatment plant is working properly is to test the quality of the effluent from the treatment plant. By doing this, you can understand which cases have exceeded the safe or low risk limit and which processes should be corrected.
Types of necessary methods for the treatment of sewage and effluents
Urban, sanitary, industrial and agricultural wastewater treatment each have different characteristics and as a result different requirements. In general, there may be three types of particles in a wastewater that can cause water or soil and environment pollution. Therefore, these particles should be removed from the wastewater through the modification of the wastewater treatment plant or its design. These particles are:
Suspended and floating materials
Colloidal particles
Soluble substances
There are various ways to treat the wastewater resulting from these particles, which can be classified under three general categories:
physical
Chemical
Ibological
